Physics as quantum information processing

Giacomo Mauro D'Ariano

The experience from Quantum Information has lead us to look at Quantum Theory (QT) and the whole Physics from a different angle. The information-theoretical paradigm---"It from Bit…

Achieving the Holevo bound via sequential measurements

Vittorio Giovannetti, Seth Lloyd, Lorenzo Maccone

We present a new decoding procedure to transmit classical information in a quantum channel which, saturating asymptotically the Holevo bound, achieves the optimal rate of the commu…

Sequential projective measurements for channel decoding

Seth Lloyd, Vittorio Giovannetti, Lorenzo Maccone

We study the transmission of classical information in quantum channels. We present a decoding procedure that is very simple but still achieves the channel capacity. It is used to g…

Informational derivation of Quantum Theory

G. Chiribella, G. M. D'Ariano, P. Perinotti

Quantum theory can be derived from purely informational principles. Five elementary axioms-causality, perfect distinguishability, ideal compression, local distinguishability, and p…

Purification of noisy quantum measurements

M. Dall'Arno, G. M. D'Ariano, M. F. Sacchi

We consider the problem of improving noisy quantum measurements by suitable preprocessing strategies making many noisy detectors equivalent to a single ideal detector. For observab…

Optimal unambiguous comparison of two unknown squeezed vacua

Stefano Olivares, Michal Sedlak, Peter Rapcan +2

We propose a scheme for unambiguous state comparison (USC) of two unknown squeezed vacuum states of an electromagnetic field. Our setup is based on linear optical elements and phot…

Teleportation transfers only speakable quantum information

G. Chiribella, V. Giovannetti, L. Maccone +1

We show that a quantum clock cannot be teleported without prior synchronization between sender and receiver: every protocol using a finite amount of entanglement and an arbitrary n…

Hyperentangled mixed phased Dicke states: optical design and detection

A. Chiuri, G. Vallone, N. Bruno +3

We present an experimental method to produce 4-qubit phased Dicke states, based on a source of 2-photon hyperentangled states. By introducing quantum noise in the multipartite syst…

Multipartite entanglement in quantum algorithms

D. Bruß, C. Macchiavello

We investigate the entanglement features of the quantum states employed in quantum algorithms. In particular, we analyse the multipartite entanglement properties in the Deutsch-Joz…

No-signaling, entanglement-breaking, and localizability in bipartite channels

Giacomo Mauro D'Ariano, Stefano Facchini, Paolo Perinotti

A bipartite quantum channel represents the interaction between systems, generally allowing for exchange of information. A special class of bipartite channels are the no-signaling o…

The quantum mechanics of time travel through post-selected teleportation

Seth Lloyd, Lorenzo Maccone, Raul Garcia-Patron +2

This paper discusses the quantum mechanics of closed timelike curves (CTC) and of other potential methods for time travel. We analyze a specific proposal for such quantum time trav…

Quantum error correction with degenerate codes for correlated noise

Giulio Chiribella, Michele Dall'Arno, Giacomo Mauro D'Ariano +2

We introduce a quantum packing bound on the minimal resources required by nondegenerate error correction codes for any kind of noise. We prove that degenerate codes can outperform…

Minimal computational-space implementation of multi-round quantum protocols

A. Bisio, G. Chiribella, G. M. D'Ariano +1

A single-party strategy in a multi-round quantum protocol can be implemented by sequential networks of quantum operations connected by internal memories. Here provide the most effi…

Information - Disturbance Tradeoff in the Estimation of a Unitary Transformation

Alessandro Bisio, Giulio Chiribella, Giacomo Mauro D'Ariano +1

We address the problem of the information-disturbance trade-off associated to the estimation of a quantum transformation, and show how the extraction of information about the a bla…

Non-equilibrium delocalization-localization transition of photons in circuit QED

S. Schmidt, D. Gerace, A. A. Houck +2

We show that photons in two tunnel-coupled microwave resonators each containing a single superconduct- ing qubit undergo a sharp non-equilibrium delocalization-localization (self-t…

3nj Morphogenesis and Semiclassical Disentangling

Roger W. Anderson, Vincenzo Aquilanti, Annalisa Marzuoli

Recoupling coefficients (3nj symbols) are unitary transformations between binary coupled eigenstates of N=(n+1) mutually commuting SU(2) angular momentum operators. They have been…
